1 Claim.

This invention relates to new and useful improvements in liquidcontainers and has particular relation to a liquid container which maybe opened without the use of any of the usua can openers or other tools.I

An object of the invention is to provide a conta-iner as for beer or thelike and which may be opened simply by pushing on a closure or seal, theuse of any tool for the opening of the container being unnecessary.

Other objects and advantages will become apparent from a considerationof the following detailed description taken in connection with theaccompanying drawing wherein a satisfactory embodiment of the inventionis shown. However, it is to be understood that the invention is notlimited to the details disclosed but includes all such variations andmodifications as fall within the spirit of the invention and the scopeof the appended claim.

Fig. 1 is a vertical sectional View taken centrally through a containerconstructed according to the invention; I

Fig. 2 is a perspective view of the container on 5 a smaller scale;

Fig. 3 is an enlarged sectional View through the neck portion of thecontainer and showing the closure or seal; and

Fig. 4 is a sectional view of a closure or seal alone and suggesting acertain modification.

Referring in detail to the drawing the container generally designated. lincludes a side or vertical wall H and a bottom wall l3 sealed to saidside wall. The container top wall [4 is also sealedto the side wall inany or the usual manner. Wall M is provided with an annular groove 15whereby centrally the wall includes a neck-like ,uportion I6.

Portion l6 stops short of the bead ll about the upper end of thecontainer, for a reason to be set forth, and the lowerpart l8 of theneck curves or inclines inwardly while the upper part l9 thereof curvesor inclines outwardly leaving a restricted place or line 20 intermediatethe ends of the neck. The outer end of the neck is provided with a bead2i.

Within the neck It is a disc-like concavo-convex seal or closure 22. Ifthe container is to be filled through its lower end the seal or closureI0 22 is inserted into place while the lower end of the container isopen. The closure is of such diameter that it must be forced past theplace or line 20 and so snaps into place against the innerside of thebead 2!. Thus the closure is mechanically held in place sealing the neckof the container and when the container is filled any gas in itscontents will further assist in maintaining the closure on its-seat. Toopen the container it is but necessary to push the closure 22 inwardlycausing it to spring past the line or place 20 whereupon it is free tosink in the contents of the container leaving the neck I6 open for thepouring of the contents 10 of the container. Thus it will be clear thatthe container may be filled with a liquid or the like andtightly sealedand that when it is desired to pour the contents of the container notools are required for the opening of the container. It is but necessaryto push the closure 22 into the container and this may be done with thefingers.

Attention is called to the fact that theneck l6 stops short of the upperbead ll of the container and that the closure 22 is within the neckwhere by in packing and shipping the containers the closure will not becasually pushed off its. seat. Bead [9 at the outer end of neck l6 alsooffers protection to the seal or closure 22 against casual contact withany surrounding objects. 7 25 Fig. 4 suggests a variation wherein theseal or closure 22a is provided with a wire or other extension 25whereby the closure may be placed in a container and the bottom of thelatter sealed after which the container may be filled through neck l6and then by pulling on. the wire 25 (which is extending through the neckof the container) the closure may be moved or drawn onto its seatagainst the inner side of bead l9. Thereafter the wire 25 will be brokenoff at the closure so. as not to be in the way or likely to cause casualopening of the closure.

Having thus set forth the nature of my invention, what I claim is:

In a container, a body including a neck, an

outwardly flared seat in said neck, a closure within said neck andcomprising a concavo-convex spring metal disk having its edge radiallyinclined toward the concave surface, said disk normally seating in saidneck with its convex surface bent
